the backward stroke of the piston. Preferably on the other side of thecylinder are 10 ,valves 12, which close exhaust-ports 13 and ll. Thesevalves arepreferably provided with sleeves heads, and collars,substantially iike those on the valves 5. A spring 2d'is interposedbetween .the nut 17 andthe collar :5 19 of these valves 12, which iscomparatively strong, so 'as to keep said valves firmly upon their seatsexcepting when the cam 21 strikes the lower end'of the valve-stems 18and raises. The.

them elf their seats at the proper time. so cylinder-head 22 fits overthe top of the cylinder-casing and is preferably provided with a recess23 and extensions thereof 24 and 25, which'fit-ov'er the valves 5 and12, respectively, and in this way make'connection be- :5 tween thevaporizing-passages 4 and said cyl- 'ildel and between said cylinderandexhaustports 13, respectively.

It will be seen that in this embodiment of my invention the vaporizerisapplied directly to the face of the cylinderand the fluid to bevaporized is discharged into a passage within the cylinder-casing andnear the combustionchamber, which is on this account kept extremely hot.This insures a quickvaporizing of the fluid, which when one oi thevalves 5 is raised passes out into the cylinder or 'combustionchambers'12. .It is a' common detect in these engines for the parts immediatelysurrounding the points where the vap- 0 oriziug takes place tobecomechilled on account of the loss of heat resulting therefrom, andconsequently such vaporization is retarded. In this embodiment of myinvention, however, this is almost entirely prevented, 3 for theatomizer discharges directly into this hot vaporizing-passage and hasonly to pass the valve 5 to enter the combustion-chamber. This almostentirely prevents any cooling of the vapor.

The overflow construction keeps the oil at a certain level, so that itis supplied to the atomizer ata uniform rate. 4 I I is a valvescrew-threaded into the casing and having an actuating knurled head 1",a shoulder R, and a conical projection S to regulate the flow of hold tobe vaporized, as shown.

The operationot this embodiment is as follows: ,Oil passes up throughthe'tnbe L and rises to the level of the atomizer and is kept at thislevel by the overflow-pipe M. When the piston moves backward, (in Figs.7 and 8 downwarth) air is drawnin through the opening Ii into thepassage 4 and draws in the form of spray a certain amount ofoil out ofthe atomizer. This amount is regulated by the position of the screw 1,carrying the valve 'one of my atomizers is necessary, and it will S.As-soon as the piston starts to move backward a partial vacuum isproduced ahead of itand the inrush of air resulting therefrom 7o raisesthe valve 5 off its seat. As soon as the spray of fluid enters the hotpassage 41t1s converted into vapor, and as the valve 5 is now off itsseat it rushes out into the combustion-chamber or cylinder ready to becompressed on the return stroke of the piston and ignited in the usualor any suitable manner.

, Of course it will be evident that a one-cylinder engine may be usedand that then only 8 0 be evident that mauy'moditications of thisconstruction may be made without departing from the spirit of myinvention.

It will be observed by my invent-ion no r;

'nlation of the air-supply is necessary, as the piston draws in therequisite amount, and the only regulation necessary to be used in thisembodiment is the regulation of the oil-supply, which can beaccomplished by means of the screw I. In this way the amount of vapor 9osupplied may be regulated by the oil-supply regulation alone.

What I claim is- 1. In a vaporengine in combinationa cylinder-casinginclosing two cylinders, a pair of vapor-passages also inclosed by saidcasing and located near one end of the same and each connected with oneof said cylinders'said passages opening through one side of said casingclose together, a vaporizer, applied directly to said casing over andcovering said openings from said vapor-passages, having a pair of atomizing-nozzles, a fluid-supply connected therewith, each of said nozzleshating a plurality of atomizin'g-points and extending into said casingand directed toward said vaporpassages, and an air-passage past each ofsaid nozzles and connected with said vapor-passages to spray said fluiddirectly into said vapor-passages.

2. In a vapor-engine in combination a cylinder-casing inclosing twocylinders, a pair of vapor;passages also incloscd by said casing andlocated near one end of the same and each connected with one of saidcylinders said passages opening through one side of said-casingclosetogether, a vaporizer, applied directly to said casing over and cover.-ing said openings from said vapor-passages, having a fluid-chamber, apair of atomizingnozzles connected therewith each of said nozzles havinga plurality of atomizing-poiuts, means to keep said fluid in saidchamber substantially on -a level with said nozzles, said nozzlesextending into said casing and directed toward said vapor-passages, afluid-inflow into said chamber and an overflow therefrom,-

and an air-supply passage past said nozzles and connected with saidvapor-passages to spray said liuid directly into said vapor-passages,and a valve between said fluid chamher and nozzle to regulate the flowof lluid therefrom.

3. In a vapor-engine in combination, :1. cylnozzle connected to inders,a vapor-passage located through the side of inder, a casing inclosingsaid cylinder, a, vaporpassage located entirely within and at one end ofsaid casing, said passage connected with said cylinder and opening'through the side of said casing, an inlet-valve in said passage, avaporizer attached directly to said casing and covering said passage,saidvvaporizer having a liquid-fuel compartment or tank, provided with aliquid-fuel supply, and an air-passage provided with an air-supply andconnected tosaid,vapor-passage,an atomizingsaid fuel-tank extendingthrough said air-passage into said casing and directed along saidvapor-passage, substantially as described. r

4. In a vapor-engine in combination, a plurality of cylinders, acasinginclosing said'cylentirely within and atone end of said casing saidpassage connected with said said casing, an upright partition betweensaid passages, an inletvalve' in each passage, a vaporizer attacheddirectlytc said casing and over said passages, a liquid compartment ortank in said vaporizerand'a liquid-fuel supply therefor, an aircylindersand opening passage and an air-supply therefor, said airsupply beingconnected to said vapor-passages, a plurality of atomizing-nozzlesconnected to said fuel -tank and extending throughsaid air-passage intosaid casing and directed along said vapor-passages.
